Lol you didn't say all those examples . This makes more since to me. You stay on why women like penetration. The psychological breakdown of why people do what they do has been studied for centuries. From Astrology to what is called science today is essentially the study of why lol. And alot of people don't stop to ask themselves that. Studies show that you have to ask why 7 times to get to the root of the motivation or cause of action/thought. The bigger part of that is understanding if the"why" is based on social programming
. Are you doing ( fill in the blank) because you saw people at some time in your life doing this? Take the example of the guy with the sign. Is the thought(s) that brought him to the street his thoughts or a product of him being taught this is how you can express your thoughts. People will always say I am doing this just because I want to( it makes me happy etc etc) I am like ok but why does that make you happy etc. At some point you wonder if anything is your very own independent thought not influenced by the social subconscious environment your in.
